| Hazard Information | Back Directory | [Synthesis]
The production method uses maleic anhydride and mixed C5s as raw materials, generates Nadic anhydride by absorbing cyclopentadiene with maleic anhydride directly at a temperature of 0-5°C, and crystallizes to obtain a pure product; and a Cu-Ni/ZnO-ZrO2 or Co-Ni/ZnO-ZrO2 catalyst is added to the generated Nadic anhydride, carrying out a catalytic hydrogenation reaction in a high-pressure autoclave for 4-6 hours at a temperature of 100-140°C and under a hydrogen pressure of 1-4 MPa, the catalyst is filtered after cooling, and reduced pressure distilling to obtain the hexahydro-3,6-methanophthalic anhydride.[1]
